Answer 1

3) Amplitude is an important parameter of waves and is the maximum displacement of points on a wave. Stated another way, amplitude is the vertical distance between a peak or a valley and the equilibrium point. Frequency is the number of wave cycles passing a point per unit time.
1) : Wavelength can be defined as the distance between two successive crests or troughs of a wave. It is measured in the direction of the wave
2) Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency
SI unit of frequency is Hz
SI unit of Wavelength is metre
SI unit of Amplitude is metre
